And check out Kate's hair – it's tied up!
The royal couple almost looked like characters in a period drama as they toured a Great War exhibition in Marlborough called 'Knights of the Sky'.
Prince William – who, of course, had plenty of flying experience while working as an RAF search and rescue pilot – was pictured climbing into a plane as his wife looked on.
The Knights of the Sky exhibition at the Omaka Aviation Heritage Centre contains one of the world's largest collections of World War One aircraft and rare memorabilia.
William and Kate were joined by at the museum by its owner, Lord of the Rings director Peter Jackson.
As well as visiting the exhibition, the duke and duchess paid their respects to New Zealand's war dead by visiting the Blenheim town memorial and laying wreaths. They both wore poppy pins on their coats as well.
Thousands of royal fans lined the streets to catch a glimpse of the couple. William has been to New Zealand before but for Kate this is her first visit to the country.
William and Kate spent time chatting with the crowd, where they were bombarded with questions about Prince George. He was back home at Government House, their base for the New Zealand trip, being looked after by his new nanny.
Among the gifts the couple received was a teddy pair and tiny pair of booties for the prince and a friendship braclet for Kate, which she put on while on walkabout.
Kate and William had their first public engagement of their New Zealand and Australian tour yesterday, taking Prince George to a children's playgroup.
